Mild hybrids are rarely detrimental. They did wonder on German 6-cyl vehicles such as X5 and MLE. I couldn't care less either it is 375 or 400HP.... the big news to me is that the S5 will continue to have a V6..... I hate 2.XToys with a passion.

I don't disagree about a V6 being better than a 4cyl (mild hybrid or not). However, I do think Audi should be pushing the S5 power numbers higher than what's being speculated. Especially with prices continuing to rise, as well as weight, horsepower does matter to me and 375hp doesn't cut it. To each their own though.

The LCI M340i is now a hybrid and I haven't heard any complaints about what that's done to the dynamics of the car despite it only gaining something like 7HP in the process. The only comment on it is how smooth the auto-stop feature of the engine is, to the point most journalists say it's worth keeping on since you won't even notice it.

The B58 is considerably more powerful than the EA838. The question is whether Audi did more than bolt a mild hybrid system on the EA838, as doing so without further developing the engine will not be enough to compete with BMW.

I sure hope the ‘25 RS5 has a fully functional front grille. I’m not a fan of the bottom half of the honeycomb being filled in and fake looking. I’m really hoping the side-body styling is sharper than the spy photos look when the production model finally is shown to the public. Still trying to come around regarding the door frames around the windows

Cautiously optimistic…

It's a mild hybrid that's just used to power the starter motor and some accessories (start/stop etc), and helps a tiny tiny bit with electric assistance when there's turbos lag (which is almost nothing on the B58 motor). The rated hp is the same as the pre-mild hybrid setup. Most owners still complain about the start stop and either drive in Sport Mode or code it out of Comfort mode since there's no *** defeat button anymore. Point I'm making is that it's not a faster or more dynamic vehicle because of the MH. It was also introduced in the 2nd model year (2021) not the LCI.

There's a reason BMW didn't bother adding it to the big brother S58 engine in the M3/4.

Best mild hybrid feature is it keeps your radar detector from rebooting at every stop/start since accessories are powered off a separate LI battery.

And 1mpg.

23mpg city for this level of power and AWD is excellent. 15% better than the S5 and 9% more HP.... I'd still prefer my car again.

It was only the EA838 for late 2016 / early 2017, then the 2.9L and 3.0L merged as the EA839. Not too many around that remember the EA838 - it has been expunged from the records!

When I first drove the B58 in an F30, it only had around 330hp and was less punchy in the mid range than the EA839 or the Mercedes 3 litre TT V6. You could pay (quite a lot) for an M Tech chip to get it closer to the other two. Yes, BMW have lifted the power output to 375hp plus a few more from the mild hybrid battery in (very) short bursts. But that's it. On BMW's plug in hybrids with the B58, they produce less ICE power than the EA839 used in VAG products.

The B58 is not inherently more powerful than the EA839. Sure, the current version in the S5 is producing 14kW less power than the B56 version in 340. Big deal. If you looked at the Porsche and Audi plug-in hybrids using the EA839, you will find almost all of them are producing more ICE power than the B58 used in BMW hybrids. Does BMW have some catching up to do to be able to keep up with VAG?

If power is the only criteria, then the C43 was and continues to be the one with the highest power output in this specific category.

Is it likely that Audi will increase outputs for the B10 S models? Probably, but they face some complexity in terms of their global product mix.

I've noticed that. Does VAG have any way of differentating between the two engines? I've seen EA839TT and EA839T used but I don't know how official that is.
